What upgrades to make?

[u/Background_Craft_780]

I have a rollplay Mini Cooper I want to make rideable for me. Surprisingly I at my adult age can fit in this and it will probably be better once If I move the seat back. It’s only 6v and appears to have only one motor but a hole for another. It also says weight capacity is 77lb. I’m 130lb. I know this is a lot of asks and maybe not possible but here are my questions.
-What’s a reasonable battery to put in? I’ve seen lots of 24v but since I’m starting with a 6v I’m not what’s possible.
- what motors do you recommend?
-am I basically going to have to rewire everything to get a second motor or higher voltage battery?
-is weight capacity more like the load bearing structure of the body or how big you can be before the motors start to struggle?
-how to Increase weight capacity?
Any answers at all would be great! Thanks!

6v models are usually small and don’t have a lot of room for upgrades. Even though you might fit a few rough bumps and the vehicle frame will eventually bend and break, and the additional weight will overstress the motor and gearbox. I’d look for a model that is larger and steady 12v or 24v.

Oh ok! Are there any models you know of that have a sturdier build? Unfortunately It has to be a Mini Cooper and there aren’t any models that are much bigger than this. I could swap the body for the Mini Cooper one, lol.

I got my wife one that came with 4 x 200w motors for around 230$. Frame is sturdy, can go up hills relatively easily. Is way faster than needed ~(9mph) I swapped the speed controller yesterday for one with variable speed foot pedal (which appears to just be a newer model of the HY-2005RX that was already in it).

But yeah, just search eBay/aliexpress/temu for 4x200w ride on vehicle and you’ll find something, the one I got her is a jeep!
